California State Route 1

California State Route 1, also known as the Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, Coast Highway, or Great Ocean Highway (GOH), is a major north-south state highway that runs along most of the Pacific coastline of California. The highway was opened in 1934 and expanded until 1964, running from Mendocino County in northern California, through San Francisco, and down to Orange County to the south of Los Angeles. The highway has been designated an All-American Road, and it provides a scenic route to numerous attractions along the coast, as well as serving as a major thoroughfare.
